When it comes to solar panels there are two types – Blue and black in color panels.
Generally, few of the solar panels are blue in color, whereas some solar panels are black in color. The source of the color comes from the unique ways light interacts.
There are two types of solar panels monocrystalline and polycrystalline.
Differences between blue and black solar panels
Some solar panels are blue due to the silicon present in them. It is due to the anti-reflective coating. This coating helps improve the absorbing capacity and efficiency. The black solar panels are monocrystalline. It is due to the fact that they absorb more natural light. The modern solar photovoltaic panels feature silicon. Silicon is available in all modern electronics. Solar panels use silicon due to their high absorbability.
The differences come in solar panels due to the purity of the silicon in the molecule. Some solar panels have blue color as they have polycrystalline silicon. The small percentage that appears black features monocrystalline silicon.
Basics about blue solar panels
The silicon in polycrystalline solar panels features raw silicone. The cell manufacturing process leads to minimizing waste and energy use. Polycrystalline solar panels are less costly. 90% of the solar panels are polycrystalline due to the low cost. So most of the solar panels have a blue color.
Basics about the black solar panels
The silicon in monocrystalline solar cells is pure. It appears black due to the way light interacts with the silicon layer. The process of aligning the silicon is energy-intensive. There is a lot of wastage in this process. Due to which this, solar panels are costly.
Which solar panel is the best, blue or black?
The black monocrystalline and the blue polycrystalline solar panels offer various benefits. Monocrystalline panels have better efficiency. It is due to their uniformity and alignment of silicon in the solar cells. But the higher efficiency comes with a cost. Monocrystalline solar panels are costly and expensive to produce. The polycrystalline solar panels have a less intensive process. As a result, the silicon is less pure, which leads to lower prices for the consumers.
A monocrystalline solar setup is your best bet if efficiency is your objective. Polycrystalline panels are your best bet if you want the lowest price. You can choose any 250w solar panel, as It all depends on your budget.
